Touch Flash

These BS83B12-3 are a series of Flash Memory type 8-bit high performance RISC architecture microcontrollers with fully integrated touch key functions. With all touch key functions provided internally and with the convenience of Flash Memory multi-programming features, this BS83B12-3 range has all the features to offer designers a reliable and easy means of implementing Touch Keyes within their products applications.

The touch key functions are fully integrated completely eliminating the need for external components. In addition to the flash program memory, other memory includes an area of RAM Data Memory as well as an area of EEPROM memory for storage of non-volatile data such as serial numbers, calibration data etc. Protective features such as an internal Watchdog Timer and Low Voltage Reset functions coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.
